For those ARMv7 devices, which have few substitutes available and not much computation power, an approach is to work from a x86 machine and cross-compile disk-images. We will also have network booting supported soon, which will allow to do the same, but without having to write an SD card. In the meantime I would propose to close this bug, as there's not much that can be done, I think. Thanks, Mathieu
